Characterization o f activated carbon of coconut
shell,rice husk and karanja oil cake

Abstract

The studies on characterization of different type of adsorbent such as coconut shell activated carbon, activated carbon from rice husk and activated carbon from karanja oil cake has been performed. The characterization of the adsorbents includes estimation of various parameters such as proximate analysis (moisture content, ash content, volatile matter content and fixed carbon content), bulk density, BET surface area, SEM, porosity, pH, iodine number and methylene blue number. Surface area of adsorbents was found by BET surface area analyzer. The pore structure of activated carbon was observed through SEM analysis. The porosity and pore volume was estimated using mercury porosimeter. The adsorbent that showed best surface properties was used for adsorption of methylene blue dye. Adsorption capacity of the activated carbon was determined to access its maximum potential for methylene blue removal
